GAS-COCK-LOCKING DEVICE FOR GAS RANGES.

Application filed February 3, 1925. Serial No. 6,635.

My invention relates particularly to the gas cocks employed in gasranges for controlling the gas supply to the broiler and oven burners,and has for its primary object to prevent the broiler cock from beingturned when the oven cock is in use and the oven cock from being turnedwhen the broiler cock is in use.

To this end my invention consists in its entirety of a locking platearranged to slide over, bar and lock the handle ofthe broiler gas cookand at the same time uncover unlock the oven gas cook, and to slideover, bar and lock the oven gas cock as it uncovers and unlocks thebroiler gas cook, all substantially as hereafter described and claimed.V

in order that my invention may be fully understood, I shall firstdescribe in detail the mode in which l at present prefer to carry theinvention into practice and then distinctly claim the same.

Reference is to be had to the accompanying drawings forming part of thisspecilication in which like parts are designated by the same numbers inall the figures.

Figure 1 is a front elevation showing part of a gas range, the oven andbroiler gas cocks thereon, and a locking device embodying my inventionapplied to the broiler and oven gas cooks, the broiler cock being showncovered and locked and the oven cock uncovered and unlocked.

Figure 2 is a cross sectional view of same on the line 2--2, Figure 1.

Figure 3 is a plan view of the locking device detached from the range.

In the drawings, d designates the breastof a gas range; 5 the left upperoven; 6 the right upper oven containing also the broiler; 7 the gas cookcontrolling the supply to the burner of the left even 5; 8 the gas cockcontrolling the gas supply to the broiler burner, and 9 the gas cookcontrolling the gas supply to the right oven, the three gas cocks 7, 8and 9 being preferably arranged in a short row below the oven 5 and 6,so that their handles all swing iuaward and to the right in the verticalplane to open them.

To lock and unlock the broiler and oven gas cocks 8 and 9 in alternationas desired the I and )reviousl 1 set forth. I Jrefer to cast a narrowhorizontal overhanging ledge 10 along the breast of the burner, andfasten to the underside thereof by screws 11, a similar narrowhorizontal plate 12, having a flange 13 along its front edge, to bearupward against the ledge 10, and a longitudinal slot 14:, In the slot 1%are mounted to ride studs 15 formed on the upper side of a plate l6,arranged to slide lengthwise along the underside of the fixed plate 12,and sus tained thereagainst by screws 17, entering the stuns 15- andwashers 18 on the screws above the listed plate 12.

The sliding plate 16 is extended forward and downward 0 er the line ofand into the V tur f the handles of the gas .ng paths 0 cocks 8 and i},so that when the sliding plate is moved to the position shown in Figure1 it will cover, bar and lock the broiler cook 13;, turning upward, andat the same time uncover and free the oven cock 9 for use, and when thesliding plate 16 is shifted to the right it will cover, bar and lock theoven cock 9 against turning upward, and at the same time uncover andfreethe broiler cock 8 for use.

The opening of either cock is thus eiiectually prvented when the otheris in use.

The downward extension of the sliding plate 16 is preferably formedskeleton like with two openings on either side of an upright centralportion which serves as a handle for shifting it.

I. claim as my invention 1. The combination with the *angc having a pairof gas cocks thereon, and a horizontal ledge overhanging the pair ofcocss, of a guide fixed to the underside of said ledge and formed with alongitudinal slot, and a sliding plate having riding in said slot andextended onward and downward o Lite handles of t i -ng paths of thecocks into the tin and lock either cock against n (kit tocover whileuncovering and unlocking the eibinati n with the body of a p r ngehaving a pair of gas cocks thereof a guide lined to the rr e body andformed with a slot, and a s 1g plate having projections thereon ridingin said slot and mourned so as to extend into the turning paths of thehandles of said gas cocks, handle while unlocking so as to lock eitherthe other.

In testimony whereof I my signature.

ARTHUR r. GLAESSNER.
